Asuma discovers a postcard inviting him to a school reunion. However, he doesn't remember receiving it. He goes to the reunion and sees Yuki Kasama, a girl whom he once had a crush on when he was at school. He feels rather embarrassed and doesn't speak to her, but she goes over to talk to him after the reunion. After talking to her, he reluctantly asks her on a date. The next day they go to the museum and planetarium. Asuma has to go to the toilet but when he returns to his seat Yuki has gone. In the seat where she sat there is a postcard from an exhibition of photographs. Rather confused, he goes to the exhibition the following day and meets Yuki, who is looking at the photographs. She apologizes for leaving and they both sign the guest book. While walking her out, she mysteriously disappears again.
The following day at a crime scene, Noa is about to fire upon a criminal labor. Suddenly Asuma sees Yuki standing behind the labor and orders Noa not to shoot. Noa eventually stops the labor, but his team mates are confused at his actions. They could not see anybody behind the labor. Later that night, Yuki comes to the SV2 hanger to apologize for actions that day. She tells him that she will be leaving the country and she'll never see him again. She runs out, but Asuma can't catch up with her. The next day, he finds the invitation to the school reunion again, but the date is the following day. At the reunion, he asks about Yuki. His old school friends tell him that she hasn't been seen in years and no one could get in contact with her. Asuma goes to the exhibition and cannot find his or Yuki's name in the guest book. Did she actually meet him or is it all just a dream?
